Abstract: 678,945. Conveyers. WRIGHT MACHINERY CO. Dec. 8. 1949. [Oct. 21, 1949] No. :31510/49. Class 78 (i). [Also in Group XVII] A machine for filling open-topped containers comprises a continuously operating conveyer for supporting a line of containers and conveying them in one direction in a path leading to a filling station, a detent which reciprocates transversely to said path adjacent to the discharge side of the station and which is moved forwardly to position it to hold the containers against movement with the conveyer while the leading container is being filled at said station, a second detent which also recipprocates transversely to said path adjacent the approach side of said station but simultaneously with, and in opposite direction to, the first mentioned detent and which when moved forwardly enters between the leading container and the next container, rearward movement of said second detent then permitting forward movement of the containers until they are again held by the first mentioned detent, and mechanism for operating said detents comprising a lever rockable about a pivot intermediate its ends and operatively connected at its ends to the detents. Empty containers are carried by a continuously operating endless belt conveyer 18 towards a position beneath a filling hopper 44 ; the foremost container is here held stationary by a detent 66 moved in front of it and a weighed amount of, for example, nuts and bolts is fed through the hopper to the container ; a plate 156 carried by an arm 154 oscillated from a cam 162 slaps the underside of the conveyer beneath the container being filled to settle the contents therein. When the container is filled a second detent 68 is moved behind it to hold the other containers still while the first detent 66 moves back to allow the conveyer 18 to carry the filled container away. The detent 66 then moves forward across the conveyer and the detent 68 moves back to allow the next container to move to the filling position. The detents 66, 68, are mounted adjustably longitudinally at the ends of arms 58, 60, pivoted at 56 adjacent the conveyer for movement in the plane of its upper surface and disposed parallel to the direction of travel thereof. The arms 58, 60 are linked by arms 74, 76 to opposite ends of a lever 78 pivotally mounted at its centre on fixed shaft 80. The arm 78 is moved through links 86, 98 by a cam intermittently driven through one revolution clutch means. To prevent spilling during filling of a container a tubular structure 126 is moved down to bridge the gap between hopper and container, the member 126 being carried by bell crank 134, 136 moved by a lug 144 on the link 76. Specification 666,306 is referred to. 678,953. Pneumatic conveyers. BASTIN, L. Feb. 24, 1950. [March 2, 1949] No. 4876/50 Class 78 (i). [Also in Group IX] Slubbings 27 issuing from rubbing aprons 2 of a carding engine condenser are conveyed to the winding apparatus (see Group IX) bv pneumatic conveying tubes 25 through which compressed air is blown from a conduit 33. Additional blowing pressure may be provided through nozzles inserted into the tubes 25 at various bends.
